Abstract

Improper application of phosphorus chemical fertilizers does not increase crop yield. Indeed, it may cause various problems in absorption of microelements by plants, specially in calcareous soils. The present study was conducted to evaluate use of azotobacter and mycorrhiza as bio-fertilizer and phosphorus (super phosphate) as chemical fertilizer on corn crop (var. KSC 704). The effects of three factors including Azotobacter chroococcum (inoculated and not inoculated), GLOMUS INTRARADICES (inoculated and not inoculated) and phosphorus (0, 50, 100, and 200 kg/ha) was evaluated in a factorial experiment using completely randomized block design with three replications. The effects of the three factors and their interactions were investigated on some parameters such as root colonization, dry matter, Zn, Fe, Cu, Mn and P concentration in shoot tissues. The results showed that mycorrhizal symbiosis increased dry matter (4.9 %), with accompanying significant decrease in Cu (14.9 %) and Mn (9 %) and increase in P (28.8 %) in shoot tissues concentration. Application of azotobacter improved the metabolites that were effective in increasing growth of plant tissues and dry matter (7.5 %), but led to significant decrease in Fe concentration (about 6.7 %). Different levels of phosphorous significantly increased P (25.6 %) in shoot tissues while decreasing concentration of Cu (22.2 %), Fe (21.4 %), Zn (15.8 %), and root colonization (about 16.6 %). The interaction between mycorrhiza and azotobacter also increased root colonization (43.3 %), dry matter (12 %) and P concentration (48.8 %), but decreased Fe (11.8 %) and Cu (15.6 %) concentration significantly (P<0.05 %) with no effect on Zn and Mn. The triple interaction of mycorrhiza, azotobacter, and phosphorus was not evident.
